一系列具有不同生物化学含量的模型生物化学组分、微藻和蓝细菌在350摄氏度的水热条件下液化，类似于200巴的水、1 M Na 2CO 3和1 M甲酸。模型化合物包括白蛋白和一种大豆蛋白、淀粉和葡萄糖、向日葵籽油中的甘油三酯和两种氨基酸。微藻包括小球藻、微拟球藻和紫球藻以及蓝藻螺旋藻。每个模型化合物的产量和产品分布已被用来预测不同的生化组成的微藻的行为，并已验证使用微藻和蓝藻。根据微藻的生化组成，预测产量和实际产量之间达成了广泛的一致。生物原油的产率为5-25 wt.%高于藻类的脂质含量，这取决于生物化学组成。生物质原油的产率为脂类>蛋白质>碳水化合物。(C)2010爱思唯尔有限公司保留所有权利。
A range of model biochemical components, microalgae and cyanobacteria with different biochemical contents have been liquefied under hydrothermal conditions at 350 degrees C, similar to 200 bar in water, 1 M Na2CO3 and 1 M formic acid. The model compounds include albumin and a soya protein, starch and glucose, the triglyceride from sunflower oil and two amino acids. Microalgae include Chlorella vulgaris, Nannochloropsis occulata and Porphyridium cruentum and the cyanobacteria Spirulina. The yields and product distribution obtained for each model compound have been used to predict the behaviour of microalgae with different biochemical composition and have been validated using microalgae and cyanobacteria. Broad agreement is reached between predictive yields and actual yields for the microalgae based on their biochemical composition. The yields of bio-crude are 5-25 wt.% higher than the lipid content of the algae depending upon biochemical composition. The yields of bio-crude follow the trend lipids > proteins > carbohydrates.
